BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a bridge or dock anti-collisionstructure, in particular, to a low-cost and green anti-collision devicemade of a composite material, and specifically to an anti-collisiondevice made of a buffering energy-absorbing type web-enhanced compositematerial, which is applicable to piers, bridge towers, and bearingplatforms of various bridges, docks, waterborne buildings, seabornebuildings and ships and used for alleviating a collision disaster from aship, a floating ice or a vehicle.

2. Related Art

It is well-known that, accidents of collision between a ship (vehicle)and at bridge continuously occur around the world all the time, and thefrequency of accidents of collision between a ship and a bridge is farhigher than our imagination. Casualties, property loss and environmentdamage caused by accidents of collision between a ship and a bridge areamazing. Many accidents of collision between a ship and a bridge atleast lose tens of thousands of dollars, more seriously, casualtiesoccur, and the loss amounts to millions, tens of millions or evenbillions of dollars; it is more difficult to calculate enormous indirectloss. Therefore, it is especially necessary to take an anti-collisionmeasure for a bridge, whose fundamental objective is: to prevent thestructure of the bridge from being damaged due to a ship (vehicle)collision force, and meanwhile to protect the ship (vehicle) as much aspossible, to reduce the loss to the lowest extent.

Over years of research and application, multiple pier anti-collisionfacilities for collision between a ship and a bridge occur home andabroad, but the basic principle thereof is designed based on energyabsorbing and momentum buffering, and each facility has its owncharacteristic and use condition. Specifically, the anti-collisionfacilities may be divided into two types. One type is the indirect type,characterized in that in addition to a pier, an anti-collision facilityis additionally arranged, and the pier is not directly subject to aforce, to enable the pier to thoroughly avoid the ship collisionproblem. For example, the pile group manner, the thin-shellsand-building cofferdam manner, and the man-made island manner aregenerally applicable to an occasion where water is shallow and thegeology condition is good. The anti-collision method of the indirecttype is done once for all, but the shipping lane may be affected, andusually the indirect type is abandoned since the manufacturing cost isexcessively high or the condition is not met. The other type is thedirect type, characterized in that: a force is buffered and thendirectly applied on the pier, such as in a fender manner, a ropedeformation manner, a buffering material facility manner, a bufferingfacility engineering manner and a manner of a fixed or floating casingbox anti-collision facility. Generally the direct type is used in anoccasion where the shipping lane is narrow and water is deep. Generallythe fabrication expenses are economic, and the civil engineeringquantity is not large. For example, a steel box type anti-collisiondevice is adopted for Zhujiang Bridge and Shanghai Yangtze River Bridge,the energy dissipation facility utilizes plastic deformation and damageof steel products for energy dissipation. When a ship collides with thesteel casing box anti-collision device, large deformation occurs in asteel plate in a discontinuous (intermittent) structure of the outerlayer of the anti-collision structure, part of collision energy isabsorbed, and contact time is prolonged, so that the peak value of thecollision force is reduced. Meanwhile, due to structure deformation andmutual action, the direction of the prow is changed, and energy exchangebetween the ship and the structure is reduced. However, the steel casingbox generally bears collision once, repair is difficult after the steelcasing box is damaged due to the collision; meanwhile, during collision,the ship body is susceptible to damage; additionally, the steel productsare easily rusted in water over years, and maintenance expenses arehigh, so it is extremely urgent to design and develop an innovativeanti-collision system made of a new material.
